SHERIFF BILL BALKWILL, SARASOTA CO. SHERIFF'S DEPT.: We're going to release it to you. We now have well over 400 leads. We are starting to get a few names. We are following those names as we speak.

Once again, I want to reiterate about the following agencies that are involved. This team work has come together. The Florida Department of Law Enforcement. The governor has set down numerous agents from there. The FBI has set down numerous agents. U.S. Marshals. We have other local law enforcement agencies who are providing investigators for us at this time to continue to follow up every lead as immediately as possible, as we can.

We're going to continue. As soon as we get some further information, we will bring it back to you immediately.

QUESTION: (OFF-MIKE)

BALKWILL: As part of the investigation, again, we're going to take any piece of the evidence that we can have to help verify anything we get. So they probably did go over there, yes.

QUESTION: Do you have any idea what (OFF-MIKE)?

BALKWILL: No, we do not have that. No.

QUESTION: Are you working on that?

BALKWILL: Yes, we are. Any leads, like I said, once again -- people are calling in, numerous people are now starting to bring name forward to us who they think possibly this person might be. Anything that we get we're going to follow up whether it's a name or we can attach a vehicle to it, we're going to follow those leads up.

QUESTION: (OFF-MIKE)

BALKWILL: Are we questioning anybody yet? We're doing an investigation on people now. OK.

QUESTION: Other than that, how do you continue the investigation when you've been going at it now for so long? You going back over the same things?

BALKWILL: Because -- no. We go over the same things. Yes, we do. But we also get tips, these tips that are coming in on phone calls. And again, we thank the citizens, not only of Sarasota County, but the citizens of Florida who are providing us with as much information as they can so we can follow those leads up.

QUESTION: Have you been able to find the two (OFF-MIKE) witnessed this? That supposedly were out during the time of the abduction?

BALKWILL: I'm not aware of that. If they did that, that's probably one of the leads that they are trying to follow up. I'm not aware of that at this time.

QUESTION: What about all the volunteers that come forward? They want (OFF-MIKE)?

BALKWILL: Well that's going depend and, you know, and where we can eventually find Carlie.

And right now what we have are volunteers doing are passing out flyers for us, trying to get any information that they can. They're going door to door for us, they're walking up and going to businesses. This is so important to us and we appreciate all their help that they're giving us at this particular time. They're here night and day helping us. So we really appreciate that at this time.

QUESTION: Any specific locations like you had the other day on Kissimmee?
